Durable workflows
Multi-step processes that resume exactly where they stopped after a crash or a deploy.
- DBOS
- Postgres state
- Cron Triggers
What it is
Business processes made of several steps — charge, notify, reconcile, retry — that must complete exactly once even if the process running them dies halfway through.
Why we chose it
The usual alternative is a queue plus a pile of defensive bookkeeping that is rewritten badly in every project. We use DBOS, which checkpoints each step into Postgres, so a workflow resumes at the step it reached rather than at the beginning, and idempotency stops being something each handler has to invent. It runs inside the application process and against the database we already operate, so there is no separate cluster to keep alive. We deliberately did not adopt a standalone workflow engine: for the scale our products run at, the operational cost outweighed what it added.
What we build with it
Where we use it
Wherever money, messaging or third-party calls are involved and a partial failure would be visible to a customer.
